I got off on a tangent this weekend, and was messing with drag/drop of audio clips and tried this on AD, but even though they drag (and show a + over the drum dragged to), nothing takes. So then I popped open Session Drummer 3 and did the same and they *do* take. I think this came to mind because of the EDM thread a bit ago.
I am assuming the answer to the question is "no," but wanted to ask to be sure.
